Design of the optimum heat pipe heat exchanger to recover heat from flue gas of boiler in case of Chiang Mai Orchid Hotel, Thailand

This study aims to design the optimum heat pipe heat exchanger (HPHE) to recover heat from flue gas of boiler for increasing the temperature of feed water. The optimum thermosyphon heat exchanger sizing was simulated on the basis of thermo-economical method and simulation program was construct by using the MATLAB 2021b.
